Q: HELP :) PRINTER SELECTION / COMPATABILITY

HI!! I need to buy a printer compatible with my new 12" airbook. This is the model with just one c-usb port

Price is really no object, looking for the best I can get in terms of:

1. Compatible was osx captain

2. preferably wireless and also compatible with iPhone, iPad etC

3. as small as possible in size and stature

4. All in one is nice but most importantly I need it to also be a scanner - one which can scan documents of any size and preferably a bunch at a time.

does anyone have any recommendations. 

THANKS
